Official wording from the codebook

DATUM LIGT TE VER IN DE TOEKOMST OF IN HET VERLEDEN

What does the codebook say for this code?

The official wording is: DATUM LIGT TE VER IN DE TOEKOMST OF IN HET VERLEDEN. That text comes straight from the Dutch codebook. We do not translate or shorten it here. The code names the element or the situation. It does not say why that element is wrong on your file. Two consignments with DMS160AB can need a different correction.

Where does this code come from?

DMS160AB sits in table A99 FOUTCD.AANGIFTE of the Codeboek Douane, part UCC declaration handling. That is the list DMS uses when it returns a declaration. AGS or Sagitta numbers from the previous system do not belong here. A German or Belgian code does not either. Source: Codeboek Douane, part UCC declaration handling, table A99 FOUTCD.AANGIFTE, edition 2026-08-29.

Does this error block acceptance?

Table A99 does not mark DMS160AB as acceptance-blocking. That does not mean you can ignore the message. It means Customs can accept the declaration and ask for papers or a correction later. Read the location in the message before you file a second time.

How do you find the real cause?

Start from the location in the message, not from a list of fixed fixes. Put the named field next to the source document and the master data. Do not guess a cause from DMS160AB alone. The official list changes. This page follows the edition of 2026-08-29. A screenshot from last year can carry different wording. The Nationale Helpdesk Douane points to the codebook, not to a vendor list.

Frequently asked questions about DMS160AB

What does DMS160AB mean?
The codebook sets at DMS160AB the wording DATUM LIGT TE VER IN DE TOEKOMST OF IN HET VERLEDEN. That line names the element or the situation, not the cause on your file.

Codeboek Douane, part UCC declaration handling, table A99 FOUTCD.AANGIFTE, edition 2026-08-29.
Does the code say why my declaration is wrong?
No. The code names the element or the reason class. The location in the message and the master data say why it fails on this file.
Do I get an MRN with this error?
Not necessarily blocked. Table A99 does not mark this code as acceptance-blocking. Whether an MRN follows depends on the rest of the message.
May I translate or shorten the official text?
